Functional polycarbonate polyols have been synthesized by CO₂/propylene oxide (PO) copolymerizations using various Zn(II)-Co(III) double metal cyanide (DMC) catalysts bearing α-, β-, γ-, and δ-dicarbonyl complexing agents (CAs) including dicarboxylic acids, diesters, ketoester, and diketones. The resultant heterogeneous catalysts are intensively characterized by infrared, absorption and X-ray photoelectron spectroscopies, X-ray powder diffraction, and elemental analysis. The produced polycarbonate polyols are characterized using infrared and nuclear magnetic resonance spectroscopies, gel permeation chromatography, differential scanning calorimetry and thermogravimetric analysis measurements. The catalysts bearing β-, γ-, and δ-dicarbonyl CAs exhibit high activity towards CO₂/PO copolymerization and produce polycarbonate polyols with high carbonate content, wide range of molecular weight and narrow polydispersity. The functionality of the resultant polycarbonate polyols varies depending on the type of CAs and the functionality of initiators.

使用各种带有α-，β-，γ-和δ-二羰基络合剂的Zn（II）-Co（III）双金属氰化物（DMC）催化剂，通过CO ₂ /环氧丙烷（PO）共聚反应合成了功能性聚碳酸酯多元醇（CA），包括二羧酸，二酯，酮酸酯和二酮。所得多相催化剂的特征在于红外，吸收和X射线光电子能谱，X射线粉末衍射和元素分析。使用红外和核磁共振谱，凝胶渗透色谱，差示扫描量热法和热重分析法测量来表征所生产的聚碳酸酯多元醇。带有β-，γ-和δ-二羰基CA的催化剂表现出对CO _2的高活性/ PO共聚，可生产出碳酸酯含量高，分子量范围广，多分散性窄的聚碳酸酯多元醇。所得聚碳酸酯多元醇的官能度取决于CA的类型和引发剂的官能度。
